Indiana Jones 5 BuzzHarrison Ford and Co. have the 'germ' of an idea.by Orlando Parfitt

March 3, 2010 - A new Indiana Jones movie could be inching its way towards the big screen, according to Harrison Ford.

The actor told the BBC that he, Steven Spielberg and George Lucas have come up with the bones of a story for the aging archeologist's fifth adventure.

He said: "Steven and George and I are sort of agreed on a germ of an idea and we're seeing what comes of it."

Explaining the trio's working methods, he said, "The process works like this: We come to some basic agreement and then George goes away for a long time and works on it. Then Steven and I get it in some form, some embryonic form. Then if we like it we start working with George on it and at some point down the line it's ready and we do it."

Paramount would doubtless like Ford and Co. to get a move on, seeing as the previous Indy-instalment Kingdom of the Crystal Skull made almost $800m worldwide.

Assuming a sequel is greenlit and takes a couple of years to make, Ford would be 70-years-old by the time Indy 5 hits cinema screens.
